The Cisco Router is connected to the WAN on Gi0/2 and connected to the 192.168.1.0/24 LAN on Gi0/0.

The DD-WRT Device's IP is 192.168.1.3/24.

I want the DD-WRT Router to handle the incoming VPN connections (PPTP).

On the Cisco device I'm assuming I need an ACL applied on the inbound on Internet interface, TCP (and UDP?) 47 and TCP 1723 allowed from any IP and an inbound NAT setup for TCP 1723 (applied to the WAN IP?)

Thanks man. And since I'm putting the DD-WRT router on the same subnet (192.168.1.3) and no WAN IP on it, it will act only a switch right? (Other than the VPN functions). I just want to make sure it won't interfere with the current routing infrastructure.
